UPTAPERED SINGLE-MODE OPTICAL FIBER PACKAGE FOR OPTOELECTRONIC COMPONENTS ABSTRACT A package for an optoelectronic device, such as a laser, having a photo-active element optically coupled to an uptapered single-mode optical fiber which connects said optoelectronic array to an external device includes a housing having a solderable substrate to which the device is secured, a graded index lens also secured to said substrate at a distance calculated to provide a known magnification of light beam emanating from said laser and an uptapered single-mode optical fiber mechanically positioned and actively aligned to said magnified light beam to achieve optimal optical coupling to said optoelectronic device. The package includes a plurality of reference marks and surfaces such that the laser, the lens and the uptapered end of a single-mode optical fiber may be positioned for precise optical coupling using an active alignment for final adjustments. The reference surfaces include a pedestal for the laser and a plurality of stops for the lens integrally formed with the sub- strate. The package also includes a fiber tube and flange for mechanically positioning the uptapered fiber. The precisely calculated spacing based on the spacing of said photo-active element, the magnification of said lens, and the fiber positioning is achieved by mechanical means. A method of optically coupling the laser to the optical fiber includes securing a graded index lens to a substrate carrier within a housing at a distance calculated to provide a known magnification of a light beam emanating from said element, positioning and actively aligning the fiber to said magnified light beam to achieve optimal optical coupling to said optoelectronic device, and positioning the uptapered fiber securable to a flange.
